Application May 27, 1949, Serial N 0. 95,735

1 a This invention relates to flood gates such as are employed across streams.

The principal object of this present invention is to provide a durable flood gate, having depending swingable members capable of yielding when floating debris strikes the same and then returning to their normal vertical positions.

Another important object of the invention is to provide a flood gate of the above character, which is capable of being easily installed, much more so than present day gates.

A further object of the invention is to provide a fiood gate which can be readily adjusted to meet the unevenness of the stream bottom.

These and various other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawing:

Figure l is a side elevational view of the gate, this also being a section taken transversely through the stream and its banks.

Figure 2 is a fragmentary perspective view showing part of the supportin chain and one of the depending gate units.

Figure 3 is a fragmentary enlarged view of the gate unit shown in Figure 2 with parts in vertical sections.

Figure 4 is a cross section taken on line 4-4 of Figure 3.

Referring to the drawing it can be seen that numerals 5, 6 denote a pair of posts having their lower ends set in the banks of a stream as illustrated. These postsmay be of Wood, concrete or any other desirable material and these are preferably provided at their upper ends with eyes I, 8 respectively.

Numeral 9 denotes an elongated supporting chain which is connected at its ends to the eyes I, 8 and clevises may be employed at one or both ends of the chain to permit adjustment thereof with respect to the eyes I, 8.

Depending from the supporting chain 9 are gate units generally referred to by numeral In. These units are shown in detail in Figures 2, 3 and i.

Each unit consists of a pair of vertical rods ll, 12, the upper end of the rod l2 being provided with a loop 13 for embracin the rod I I, while the lower end of the rod II is provided with a loop M for embracing the rod 12.

The lower end of the rod I2 is free, while adjacent its upper portion, an opening is formed to receive a pin l which also projects laterally and through one of the openings IS in the lower portion of the rod H, and in this manner the rods are not only interconnected together but positively secured in adjusted position, this to the extent that the lower end of the rod l2 will be the proper distance from the bed or bottom of the stream.

1 Claim. (Cl. 39-4) It is probable that the upper end of the rod H be threaded as at I! and extend upwardly through one of the horizontal links of the chain 9. A nut I8 is provided on the upper end of the threaded portion ll and this rests upon the horizontal links to prevent downward displacement of the unit I0.

It can now be seen through the medium of the nut 18 and thread I! or through the medium of the pin l5 and opening l6, the rods ll, l2 can be adjusted vertically with respect to the bottom of the stream so that they will be in proper relation thereto. As many of these units as is desired may be added and suspended from the chain 9.

Obviously when debris floating down the stream strikes this group of units l0, they will swin and permit the debris to pass thereunder, then returning to their normal vertical position.

While the foregoing description sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

A flood gate comprising a pair of vertical anchor posts, a chain interconnecting the tops of said posts, and a plurality of dependin guard elements connected in spaced relation to said chain, each of saidelements comprising a vertically extending upper rod having a threaded upper end adapted to extend through said chain, a nut engaged with said threaded end to prevent downward movement of said upper rod, a laterally extending loop at the lower end of said upper rod, a vertical lower rod extending through the loop of said upper rod and havin a laterally extending loop at its upper end for receiving therethrough said upper rod, said upper rod having a plurality of spaced transverse openings in its lower portion and said lower rod having a transverse opening adjacent its upper end, and a pin extending through the opening in the lower rod and selectively through one of the openings in the upper rod, whereby the efiective length of said element may be controlled.
